A locking mechanism for fixing an outer part (5) on an inner part (4) having locking members (8) which are guided in apertures (7) of the outer part so as to be radially movable in a limited way. In the locking position, these locking members (8) are supported radially outwardly on a locking ring (10). A control ring (16) retains the locking ring in the open position. For this purpose, the control ring (16) is displaced eccentrically and is supported on a stop (19) associated with the outer part (5). By inserting the inner part (4), the control ring (16) is aligned coaxially by the control members (8) so that a spring (12) loading the locking ring (10) can act to move the control ring (16) across the stop (19) so that the locking position is achieved.

A locking mechanism for fixing a coupling sleeve of a drive shaft of an agricultural implement to a power take-off shaft of a tractor, the locking mechanism comprising locking members which are guided in apertures in the sleeve so as to be movable in a radially limited way and which, in a locking position, are supported in a radially outward direction on an inner bore face of a movable locking ring of the locking mechanism, which locking ring is loaded by the force of a spring of the locking mechanism into the locking position, the spring acting on the one hand on the sleeve and on the other hand on the locking ring, the locking members extending radially inward from the apertures into a receiving bore of the sleeve and projecting, for fixing purposes, into a recess in the shaft, and the locking mechanism also comprising means for retaining the locking ring in an open position clear of the apertures for the locking members and for automatically cancelling the retention when the shaft is introduced into the receiving bore of the sleeve, wherein the retaining means is in the form of a control ring, the control ring being movable from the locking position of the locking mechanism, with the control ring being guided over a stop projecting radially from the outer face of the sleeve and axially supporting the locking ring, into the retaining position in which the locking ring is axially supported on the one end of the control ring whose other end is supported on the stop, the control ring having a circular cross-section and surrounding the sleeve with play, and being movable from the locking position in which the stop holds the control ring concentrically relative to the locking ring and the sleeve, into an eccentric position relative thereto by an adjusting spring acting on it radially.
